Few would want to return to those days of stylus-driven interfaces, but styli can still be helpful for a number of tasks, including diagramming, drawing and sketching, signing documents and handwriting recognition. In this regard, their status has become similar to keyboards on capacitive-touch devices -- great when you need them, but a form factor compromise when you don't. So, just as the ASUS Eee Pad Transformer works with an optional keyboard, HTC will make its Scribe pen an extra, taking a tentative step toward bringing back the stylus, though not a half-hearted one -- the company allows one to write anywhere in the Sense user interface, supporting the stylus input method with the backing of software.
The pen paradox is that, for all the contention that has been fostered between multitouch and styli, the two can shine when used in tandem, assuming the user interface has been created with both in mind. This was a key attribute of Microsoft's aborted Courier
project, although Microsoft Research has also demonstrated the combination on other devices
. Demo videos show that multitouch and pen together can provide more flexibility than using either alone, although some of the combinations are far more sophisticated and perhaps more abstract than simple gestures such as swiping and pinch-to-zoom. They tend to work better on mid-sized to large screens, ranging from tablets and PCs to Surface-like displays.
Perhaps Microsoft will put that R&D to work in the next version of Windows. For that operating system, the company must create an overhaul of its user interface anyway if it is to go toe-to-toe with iOS and Android as a viable tablet experience. As an add-on to today's finger-focused touchscreens, however, the stylus continues to face pointed challenges as it overcomes its stigma. The pen may be mightier than the sword, but it will soon be tested on its ability to cut through a field of otherwise undifferentiated tablets.
